Abstract (en)
[origin: GB2484161A] A dynamo-electric machine includes a rotor 1 having a plurality of permanent magnets 3, a stator 5 having a plurality of stator coils 9, and an adjustable magnetic shunt 4, for shunting the magnetic flux of at least one of the permanent magnets 3, the shunt 4 being displaceable axially between a shunting position and a non-shunting position. The rotor 1 includes a magnetically anisotropic rotor core 11 and a magnetically isotropic core element 24 situated between the V of the magnets to increase the flux quantity14 shunted when the shunt 4 contacts the rotor end. A further isotropic core 26 may be provided inboard of the magnets (figs 11,12) to achieve even further flux diversion 14. The anisotropic rotor may be achieved by means of laminations and the isotropic core parts may be an electrically non-conductive material comprising a soft magnetic composite (SMC) of insulated iron powder particles. The prior art fig 2 shows an example of appropriate shunt control.
